SERVICE CALLS

The objective when m aking a service call is to get the custom er up and running as quickly as possible. For this reason the best method of attack is to find the problem quickly and isolate the faulty component and swap it out with the good com ponent in your dealer service kit. The defective module or part can then be repaired to returned to the factory away from the custom er's home.

W ith this objective in mind the EasyFire troubleshooting can be divided into six (6) general categories:

1.The fan and feed m otors.

2.The main circuit board.

3.The switch (control knob) circuit board.

4.The tem perature sensors T-1 and T-2.

5.The AC power line com ponents, i.e.,

6.The wiring harness and connectors thereto.

These six (6) areas represent the areas where problem s might occur. They are listed in the order of highest probability, based on their history and level of complexity. The design of the electronics has been done with reliability as the highest priority, and the com ponents which are under the most electrical or therm al stress are very conservatively rated.

The main board has been listed second due to the large num ber of parts, which increases its chances of failure on a statistical basis. In practice, however, it should be the most reliable due to the rigorous test procedure each board goes through before being installed on the stoves. Because of this mechanical item s such as the motors should be suspect first. Rem em ber, ninety per cent (90%) of pellet stove failures are due to im proper maintenance by the end user! Check the stove for cleanliness and routine maintenance before doing any mechanical service work.

Following is a list of complaints and/or service problem s which represent at least ninety five (95% per cent of possible service calls:

1.Stove not running at all.

2.Feed m otor runs, but no fan.

3.Fan motor runs, but no feed.

4.Stove runs, but shuts down about 10 m inutes after start up.

5.Stove runs, but keeps shutting down with over-tem p (red) LED coming on.

6.Stove runs, but heat output rem ains at the LOW level, even when switch is on HIGH.

7.Stove does not run on battery or battery does not charge.

8.Stove runs on FAN position but when switched to LOW , MEDIUM or HIGH shuts off imm ediately.

9.Stove seem s to be running very HIGH or CLEAN mode at all times.

10.Fan speed seem s norm al for each position, but feed rate seem s excessive even on LOW .

Following is a trouble shooting Flow Chart for each of the problem s outlined above. If you follow the flow chart carefully each of the problem s can be solved quickly and easily.
